If you design and develop electronic components and devices, one of the most important things that you need to do is to lay out a design of what ever you are trying to build at the very outset, and get it tested so that you know that there is all the functionality in your creation that you are looking for. One of the most important tools that circuit designers and electronics developers use to ensure that their designs work as expected and can be replicated for sale is choosing to use printed circuit boards or PCBs print their designs onto. A printed circuit board is a flat board made out of nonconductive material with a layer of conductive material on top which has the circuit connections hard printed into the board, on top of which the different components of electronic circuits can be mounted to hav
